In that case, Bernie, then all talk of multiverses are supernatural
speculations - since anything beyond our universe (and certainly 'outside of
time') has typically been called such, before it was necessary to turn to
such ideas to potentially account for the Big Bang/Fine-tuning. Ergo, a
multiverse generator is supernatural. Indeed, why not go the whole nine
yards and - since we're now imagining an entity capable of 'creating
universes' - outright speculate that what we're talking about may actually
BE God. Complete with omnipotence, omniscience, etc.
